Bad Support from Dyson SA

I have been battling with Dyson SA for Rollers for the Dyson Wash G1 machine but they have been telling me they are sourcing such from oversees. now they do not respond via email and have gone quiet on me. For such expensive equipment they are pathetic - to say the least and the public should stay away from them. I have been dealing with a person called Razia but does not respond to any emails.
